I've found problem with NIS schema. I don't even know how it possible, but object class posixAccount have no enough attributes, like homeDirectory. Somehow that attribute was placed into extensibleObject class.
I've tried to reinstall ApacheDS AM25, because thinked what I doing something wrong, but no, problem wasn't fixed! Last try was - install M24, and after that I've checked NIS schema in that build, and it was OK.
